How setup a DVR and a internet router for remote viewing

You may have many problems for how to have a remote viewing by DVR and a internet router. Then here firstly you should connect your DVR to your router
 Use menu on DVR to assign internal IP and gateway and port number.
This Local IP must be in the same Gateway range as the Router. If you are unsure check the Router and locate the Status section or goto the Command prompt of Windows XP and type in ipconfig.
Look for Gateway. If the Gateway is 192.168.1.1, then you can make the DVR's IP anything from 192.168.1.2 - 192.168.1.255.
Also you will need to use the same SubNet Mask, which is typically 255.255.255.0, and also use the same gateway.
Next find out what port your DVR uses. The easiest way to it is by reading the manual of your DVR. Look for the network section of it.
Also if it comes with network software, check out if in the connection area the software shows the port number.
Also check the Server software/Programming (Network section of it) to see if the port is listed.
In many cases it will be as simple as just Port 80, which is an HTTP port.
Set your router to forward chosen port to internal IP address of DVR.
To access the Router itself, use the Gateway you just located. If the gateway is 192.168.1.1, then enter that into the location edit box of your browser and then click the Enter button. A username and a password are typically required, but it depends on a router. For Linksys use "admin", "admin". By default DLink doesn't require any username or password (It is highly recommended to change the default password).
Once you're logged into the Router, in the Applications & Gaming Section / Servers of the Router, you need to add a Server/Application. Enter the port number and select TCP only. Where it says Port 0 to 0 enter the same port number twice. Or if your DVR uses for example, ports 3550, 4550, 5550, 6550, and there is nothing else utilizing these ports in between, then you can actually just enter one line, 3550 - 6550.
Enter the DVR/Cameras internal IP.
Enable it.
Set up additional entries for as many ports the DVR uses, to the same local IP. Check your DVR manual and it's networking section for all additional ports required. Also check the DVR software itself.
If your router has enough free entries, you can seperate them. Use it like DVR_HTTP for the browser port, DVR_AUDIO for the audio port, etc.
If you are going to use VNC to a PC DVR, then you would need to set up port 5900, and perhaps call it VNC_DVR, for example.
You have a static IP so you don't need to use sevices like dyndns . You just enter your static IP and your router forwards packets to your DVR.

DVR replaced VCR or not?

A DVR, or called digital video recorder is the modern equivalent of a VCR. DVRs digitally record movies, TV shows and other videos. DVRs have high-capacity built-in computer hard drives which can store many hours of video and can erase and record over data almost indefinitely. DVRs can come with TiVo or another service which they are designed to work with. They can automatically record programs from that service for later viewing.
Different DVRs receive their digital signals from different sources. Depending on the service, the DVR receiver might get a signal from a conventional cable, fiberoptic cable or satellite dish. If you set the DVR to record while the TV is on, the receiver automatically divides the signal into two. One signal is turned into an image which is displayed on the TV screen, along with a soundtrack played on the speakers. The other signal is written directly onto the hard drive of the DVR. When you want to watch the program again, the hard disk reads the stored signal and turns it back into video and audio for your television. DVRs also have timers which allow the user to cue the DVR to record a particular show. When the timer goes off, the hard drive switches to the preset channel and records the incoming signal until the timer automatically turns it off again.
There are several advanced features available on modern DVRs. Many DVRs can actually record one show while displaying another on the television. These video recorders actually have two tuners so one can record the show on one channel while the other displays the show on another channel. Another popular feature is the ability to pause live broadcasts. When the DVR user hits the pause button, the hard drive starts recording the broadcast. When the user hits play again, the DVR actually plays him the recording, while continuing to record the show as it comes in.
And now there are many places,such as bank,supermarket and gas station ect. use DVR system to secure their belongings’ safety. You can click http://www.ecvv.com/product/2714238.html to know more about DVR.Also,china DVR suppliers,china DVR manufacturers,china DVR also are displayed on it.
